Feature Enhancement: Better Tooltips

[MTadder]

Currently, tooltips that are shown after hovering the mouse over script items do not differ from the item's label.
#90 is a proposed, and highly compatible fix.

I don't see much value to be honest. I checked other IDEs and they all just show the text.
The Tooltip is useful when the outline is truncated, so you can read all of it.
That is why everything is color coded (instead of having no icon at all), so you can quickly see what it is. No need for a special Tooltip or something else.

Note: What would be nice is if we can give a tooltip on the icon. That is also done in IntelliJ and explains the icon again. I think this would be a nice addition. But AFAIK, this is not supported in Godot right now (We can only set a tooltip for the whole item):
